'74 Taillight Questions

[Super_Dave]

I have not brought myself to be able to update the disaster that happened to my '74 build as it sat in a shop 90 miles away for 15 months of work. Short story, my brother, myself and AAA hauled it back home.

I am trying to formulate a plan to repair thousands of dollars in damage while not dropping any more bundles of cash.

To that end, and because I have to repair body damage and paint anyway, I am considering the following:

The taillights are OEM, as is the bed. The taillights have ridiculous gaps between the top and the bed... I can stick a full finger tip in the gap. Maybe that's the way all squares are. So, since I have been going with the shaved theme on the moldings, I want to weld in a set of MAR-K Taillight Fillers. This will require adding some sort of taillight assembly.

Question #1: (photos please)
Has anyone used the MAR-K taillight fillers and how did it go?
Has anyone deleted their Squarebody OEM taillights and what did you replace them with?

Since I want the shaved-smooth look, I will also be smoothing out the tailgate with the MAR-K filler that leave room for the release handle, or the full tailgate cover with a handle relocation kit.

Question #2:
Has anyone used either of these MAR-K products? They appear to be accurately produced from good material and the price seems very reasonable and it would save me a lot of fabrication time. . . and open up potential lighting locations for Billet LED Taillight and Brake Light Inserts..
